IMPROVEMENT IN HAV-ELEVATORS.

The Schedule referred to in these Ill-etten Patent and making part of the same.

ence being had to the accompanying drawing and to the letters of reference marked thereon and being a 'part of this specilication, in which- Figure 1 is an elevationof my device in operation;

Figure2 is a detached perspective view of the trav-A eler; and

Figure Sissa cross-section of the same.

Like letters indicate like parts in each figure.

The nature of this invention relates to aix-improved device for elevating hay in a barn, and conveying the same lto the vpoint in the hay where it is desired to dulnp it; and

Ithfconsists in the novel and peculiarconstruction and'method of operating a traveler or conveyer on a single Irail suspended from the rafters of the barn by means of a hand-rope, said traveler carrying a hayfork provided with a tripping-line, and operating as hereinafter set forth.

In the drawingv A A' represent a horizontal rail or stringer, of wood, .suspended from the rafters, near the roof ofthe barn, by iron rods, B, passing through the center thereof. The shorter of the rail-sections has the end of the longer one overlapping it, said end being scarfed to an angle, as shown in Iig. 1. lhe short section is designed to be directly over the door on which 'the loaded vehicle stands, and, if the barn has bays at each side thereof, the long section A should extend each way from the shorter one to the ends of the barn.

`C is the traveleror conveyer, preferably of iron, having its upper part forked, and at the extremities of the forks are inwardly-prqiecting studs carrying .rollers, a, which move upon the outer edges of the horizontal rail, clearing Vin their passage the central v supporting-rods thereof', as shown in igs. 2 and 3.

In-the lower part of the traveler a sheave, b, is pivdted, and eccentrically thereto a. hail, c, is also pivoted therein, passing around the sheave above the central plane, andhaving attached thereto the hand-rope D,

' passing over a sheavc, E, suspended from the rail-section A.

.To the eyeof a hay-fork, shown at F in iig. 1, the theelevating-rope G is attached; thence led over the sheavel) in the traveler, passing under the bale c;

thence along the under side 'of the rail A to the outer `end thereof, over a "sheave, H, suspended from-1i, dow'n to a proper'guide-pnlley secured to the oor, and thence out of the barn, where the teamis attached to its other end.

Any hay-fork having a trippingsline to discharge its load may be used.

Ihe action of the bail c is to wedge the rope G intc the groove of the pulley b as soon as a downward strain is exerted on the end having the fork attached thereto, thereby preventing the loaded fork from running down, unless the bail be raised by the handrope. v

Ihe operation of my improvement may be described iu the following manner: w

The loaded wagon being on the floor, and a team attached to the elevating-rope, the latter is slacked up, so that the operator standing on the load may, with the hand-rope, draw the traveler toward hixn'. He then inserts the fork in the hay, and causes the team to be started forward, which will elevate the fork and its load to the traveler, which in the meantimerexnains on the rail A, when the continued draft compels-.the carrying-wheel cl to travel up the inclined plane at the end of the long rail, and thence along it t0 the outer end, when the team is halted, or over any desired point in the bay, where the load is discharged by pulling on the tripping-line. rIhe team is then backed up, and the operator draws/back the traveler by the hand-rope, and the above-described operation repeated.

Ihe pulley E should be so placed that its top will be on a plane above the bight of the ball when the traveler is on the short rail, and below it when on the long rail. In the former instance a stra-in ou the hand-rope withdraws the bail from contact with the hoist-rope; in the latter it does not.

Vhat I claim as lny invention, and desire to secure by Letters Patent, is

1. 'lhe traveler G, having two upper branches, each provided with a roller, a, a sheave, b, and bail, '0, all constructed substantially as described and shown, and

arranged as and for the purposes set forth.

2. In combination with the traveler C, constructed as described and shown, the rails A and A', the. halidrope D, the hoist-rope G, and the pulleys E and I-I, all constructed and arranged substantially as dcscribed and shown, for the purposes set forth.
